Obviously, instead of applying the toothed wheels in mortises in the sash, they may be placed outside of them, and by further rearrangement of parts the racks and the wheels and their appurtenances might change places on the window.

By this invention I provide a sash hoisting, locking, and tightening device, which may be readily operated by one hand and which obviates the tugging and exertion commonly necessarily put forth in operating Windowsashes as usually constructed.

WVhat I claim is- 1. An improved window-sash hoisting, lockpivoted dogging devices having oblique slots in one end and feet on theother end, stationary plates having straight longitudinal slots therein intersecting the oblique slots of the dogging devices, toothed racks engaged by said dogging devices, rods connected by hooks t" at one of their ends with said dogging devices through said slots and attached at their other ends to the ends of a rigid bar extending across the bottom edge of the sash, springs fastened to said rods and bearing against ab ntments on the stationary plates normally to raise said rods and throw and hold the dogging devices in engagement with the toothed racks, and a push-piece attached to said bar and adapted to operate said dogging devices through the bar and rods, to unlock, release, and loosen the sash, and also to permit said dogging devices to lock and tighten it, in 00mm bination with sash-balancing devices, such as toothed racks, substantially in the manner and for the purpose set forth.

2. An improved window-sash balancing, hoisting, locking, and tightening device comprisin g a balancing medium, preferably coiled springs incased in hollowtoothed Wheelswhich are held in position in the sash or frame by suitable cases, face-plates on such cases having straight longitudinal slots and toothed racks or plates adapted to engage and turn said toothed Wheels, a flat movable cross-bar,

a push-piece attached thereto, and rods conone hand be raised, stopped, locked, and tightened or loosened and released at any desired position, in the manner described, and substantially as and for the purposes set forth.

In testimony whereof I have hereunto set my hand this 18th day of June, A. D. 1892.
